Definitions
- This disclosure relates to composite films that are liquid impermeable and moisture vapor permeable.
- Films that are liquid impermeable and moisture vapor permeable have many applications. These include use in apparel, upholstery, fabrics and protective layers on flooring and carpet pads. These films are usually made from synthetic polymers such as polyethylene or polypropylene.
- Carpets or rugs are typically installed over a carpet pad that includes a resilient cushion material.
- the purpose of the pad is to make the carpeted flooring surface feel soft and luxurious to those walking on it.
- carpet pads are formed from polymeric materials such as synthetic latex rubber, natural rubber and polyurethane, all of which are distinguished by their ability to deform and recover.
- polymeric materials such as synthetic latex rubber, natural rubber and polyurethane, all of which are distinguished by their ability to deform and recover.
- One of cheapest and most common materials used for carpet pad is an agglomeration of foam pieces, usually of polyurethane, called rebond.
- Moisture retention in the cushion material also presents a problem for moisture passing upwardly from the floor.
- Most floor surfaces transmit water vapor from locations of higher humidity beneath them, whether from the ground, the basement, or even the room below, and the volume of this moisture is often surprisingly large. It is therefore very important that any water vapor from beneath the floor be able to pass through the carpet pad. That is, the pad should be permeable to moisture vapor. Otherwise, the base flooring may be exposed to condensation moisture, again resulting in mold or bacterial growth and damage.
- moisture vapor permeability This ability to transmit water vapor is called “moisture vapor permeability”, or “breathability”, and is measured in terms of moisture vapor transmission rate (MVTR).
- the Carpet and Rug Institute, Dalton, Ga. recommends an upper limit rate of moisture vapor transmission through a floor to be 14.6 to 24.4 grams per square meter per twenty-four hours (14.6 to 24.4 gms/m 2 /24 hours) as measured by ASTM test E96B.
- MVTR moisture vapor transmission rate
- the MVTR of the film is needed to ensure that the required amount of vapor is transferred through the carpet pad and not trapped under the film. It is desirable to keep the film as thin as possible to reduce the costs involved. The challenge with using a thin film that is cheaper to make is that it often lacks the robustness necessary to survive use, causing tearing and ineffectiveness.
- U.S. Pat. No. 6,253,526 discloses a process for installation of carpet in which the critical properties of breathability and water impermeability are resident in an underlayment that is separate from the padding. While the underlayment is effective in achieving both desired moisture vapor permeability and resistance to spills it requires a separate installation step which is not cost effective and is therefore not widely used.
- WO Publication 01/27382 A1 describes an underlayment for a carpet having the desired properties of moisture vapor permeability, liquid impermeability and durability that is maintained under the pressure of cleaning and that would be tolerant of normal foot traffic on the carpet above.
- the structure of this underlayment uses a laminated substrate of fibrous material, which significantly adds to its cost.
- U.S. Pat. No. 5,531,849 discloses a pad having a smooth polyurethane foam layer disposed between two film layers.
- Canadian Patent 2,320,471 describes an underlayment with a liquid impervious film formed over containment channels to hold spills near the point of introduction and make them easier to recover.
- these pads are not breathable and the durability of both of these pad structures and the ability to retain liquid imperviousness is highly dependent on the thickness of the film layer employed.
- U.S. Pat. No. 6,872,445 herein incorporated in its entirety, teaches a carpet pad that utilizes a synthetic polymeric material directly bonded to the upper surface of the cushion that is simultaneously impermeable to liquid deposited onto the pad from above the barrier film, and permeable to moisture vapor at a MVTR of at least 14.6 g/m 2 /24 hr.
- a film of thickness of at least 0.5 mils, but usually much greater, must be used. Because these breathable films are expensive, this adds to carpet pad costs.
- U.S. Pat. No. 8,283, 029 teaches composite films comprising multiple layers of barrier film layers.
- the films of this disclosure do not feature the robustness necessary for applications such use with carpet pads and often require the use of a nonwoven layer.
- the present disclosure relates to composite films of at least two film layers wherein at least one film layer is a barrier layer which is liquid impermeable and moisture vapor permeable.

- the apertured layers have holes having diameters from about 1 to about 100 microns in length.

- Another aspect of the present invention relates to a carpet system comprising a carpet pad comprising
- Yet another aspect of the present invention relates to a method of making a carpet pad comprising a) providing a carpet cushion having an upper and lower surface thereon, b) providing a composite film comprising one or more barrier layers and one or more dimensionally stabilizing layers, wherein the composite film achieves a moisture vapor transmission rate (MVTR) according to ASTM E96B of from about 50 to about 4500 grams/24 hr/m 2 , prior to bonding said composite film to said upper surface of said carpet cushion, and c) physically bonding said composite film to said upper surface of said carpet cushion.

- Example 15 the composite film described in Example 15 is robust as well as provides acceptable MVTR.
- Such a composite structure could use very thin barrier films with high MVTR and also ensure there is no liquid penetration as the barrier film is impenetrable.
- the structure can be optimized for cost, MVTR, robustness and penetration by liquids.
- An adhesive layer can be additionally added to ensure good bonding between this composite structure and cushion.
- ratios, concentrations, amounts, and other numerical data may be expressed herein in a range format. It is to be understood that such a range format is used for convenience and brevity, and thus, should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited.
- a concentration range of “about 0.1% to about 5%” should be interpreted to include not only the explicitly recited concentration of about 0.1 wt % to about 5 wt %, but also the individual concentrations (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.5%, 1.1%, 2.2%, 3.3%, and 4.4%) within the indicated range.
- the term “about” can include ⁇ 1%, ⁇ 2%, ⁇ 3%, ⁇ 4%, ⁇ 5%, ⁇ 8%, or ⁇ 10%, of the numerical value(s) being modified.
- the phrase “about ‘x’ to ‘y’” includes “about ‘x’ to about ‘y’”.
